IMPROVEMENT IN COMBINED PENClL-SHARPENER, ERASER, AND TABLET.

Specification forming part of Letters Patent N 0. 217,446, dated July15, 1879; application filed March 20, 1879. e

To all whom it may concern: Be it known that I, HENRY CLAYTON, ofDayton, in the county of Montgomery and State of Ohio, have inventedcertain new and useful I mprovemcnts in Combined Pencil- Sharpener andEraser; and I do hereby de clare the following to be a full, clear, andexact description of the same.

My invention is an improvement in devices for school and office use; andconsists of a pencilrsharpener. an eraser, and a tablet or writing-surface, all being united together in a compact and convenient form,as a new article of manufacture.

Inthe accompanying drawings, Figure lis a plan view of my device. Fig. 2is a longitudinal sectional view of the same through linexa: of Fig. 1.

The body of the device consists of a block or base-piece, A, of anysuitable or desirable size,shape, or material-preferably, perhaps, ofwood, and rectangular in form. Upon one or more of the broader faces ofthis block is formed a tablet, B, ruled and lined, if desired, forwriting upon. This tablet-surface may be produced by coating the face ofthe block itself with artificial slating, or by pasting or otherwisesecuring upon its face a thin plate or slab of slated paper or similarmaterial, of such a kind as will readily permit pencilma: ks to bereceived on its surface, and as readily permit of their erasure. positeface of the block may be pasted a piece of cloth or buckskin, F, or thelike, for use in cleaning slates.

At one end of the base-piece A is fastened an ordinary piece of rubber,D, such as is com-' monly used for erasing lead pencil marks. Thiseraser may be secured in place by gluing or riveting its end in a grooveprovided for it in the end of the block A. At the opposite end of saidblock is the pencil-sharpener. This consists of a blade, E, insertedtransversely Upon the op- H in an inclined slot, 8, cut in the end ofthe base-.piece to receive it. This slotv should incline obliquely fromthe top surface or edge of the base-piece downward and toward the rear,so as to give to the blade, when embedded therein, a correspondingslope. The blade may be removed for sharpening. That edge of the bladewhich, when it is in place, is presented outward is sharpened forcutting. To render this cutting-edge easily accessible for use insharpening pencils, two depressions or recesses are cut in thebase-pieceone set, a, on its top surface, above the blade, and an:other, b, on its end face, just beneath the blade. These recesses permitthe cutting-edge of the blade to project out, so that a pencil may bedrawn transversely across it in sharpening,

= and at the same time they permit the blade to be embedded in the baseA deep enough to prevent it from oflering a cutting-edge at any otherpoints than at these recesses, so that the device may be carried in thepocket without danger of the knifes cutting or injuring the same.

By the above construction I provide a simple, compact, and veryconvenient device, which will be found especially useful forschool-children, clerks, and the like.

Having thus fully described my invention, I claim as follows:

As a new article of manufacture, the hereindescribed combinedpencil-sharpener, tablet,

" and eraser, consisting of the base-piece A, inclined embeddedcutting-blade E,tablet B, 'aud erasers D and F, the parts constructedand relatively arranged in the manner and for the purpose specified.

Witness my hand this 17th day of March,

HENRY CLAYTON. Witnesses:
